Okay...the police have equipment that can look into your house and see activity through the walls. You go to the airport, and the screeners can give you a remote colonoscopy, looking for weapons. Doesn't our military have something that would let them see the activity, and look for explosives within the mosques?
I agree. If they object to an infidel going in, we can send American Muslims (Not that I trust them as much, but it's a start). Why can't we have a team of American Muslims go in with bomb sniffing equipment. I presume that a bomb sniffing dog would upset them.
Then if they refuse we threaten to level the mosque. If they stil refuse we level the mosque.
It's a shame that there isn't some kind of beam we could zap a mosque with that would cause explosives to detonate. We could just go around candestinely zapping the mosques and see which ones blow up.
